Was Walter McCrone a member of STURP?
In a word: no.
Despite the fact that Walter McCrone claimed that he was a member of STURP, he never was. He wrote that he had been "drummed out" of the group because they did not like his conclusions. What is true is that the members of STURP did not like his conclusions. The were absurd in light of all the evidence gathered in Turin.
McCrone refused to agree to STURP’s professional standards agreement including non-disclosure. He was thus not accepted as part of STURP.
McCrone claimed also that STURP, upon learning of his findings, confiscated his samples and that STURP brought in other scientists to replace him. None of this is true.
Ray Rogers had collected 32 sample tapes that included thousands of particles of matter taken from the Shroud. On his way back to Los Alamos from Turin, he stopped in Chicago and loaned the samples to McCrone. There were two stipulations:
- The samples were to be studied by microscope in situ. Particles were not to be removed from the tapes.
- The samples were to be returned as soon as McCrone had examined them.
McCrone violated the agreement. He damaged some of the sample tapes and then he refused to return them. Finally, Rogers had to fly to Chicago to retrieve them.
